Small ERB Implementation
Erubi is a ERB template engine for ruby. It is a simplified fork of Erubis, using the same basic algorithm, with the following differences:
* Handles postfix conditionals when using escaping (e.g. <tt><%= foo if bar %></tt>) * Supports frozen_string_literal: true in templates via :freeze option * Works with ruby's --enable-frozen-string-literal option * Automatically freezes strings for template text when ruby optimizes it (on ruby 2.1+) * Escapes ' (apostrophe) when escaping for better XSS protection * Has 6x faster escaping on ruby 2.3+ by using cgi/escape * Has 86% smaller memory footprint * Does no monkey patching (Erubis adds a method to Kernel) * Uses an immutable design (all options passed to the constructor, which returns a frozen object) * Has simpler internals (1 file, <150 lines of code)
